Intermediate Stage Build of Sheet Metal in Progressive Die Design

摘要

Intermediate stage build of Multi-station progressive die is to get intermediate configuration of every station and blank by unfolding product configuration reversely. It needs complicated hand computation and drawing to design intermediate stage with traditional method. In this paper, NX PDW module is used to finish the work. According to the shape of sheet metal, parts are simply classified into three types, and for different type of sheet metal part, different method to unfold the product configuration is discussed. The process of building intermediate stage with PDW is intuitive, timesaving, and also easy to modify.
